SETH ENGLAND, 30

CRAIG WISEMAN, 52

Wiseman is still writing hit songs — such as Blake Shelton’s “Came Here to Forget,” which topped the June 11 Country Airplay chart — but he also administers publishing for a stable of ­songwriters at Big Loud Shirt. Their success has put the company among the top 10 music ­publishers in 12 of the last 15 quarters. He sold a chunk of equity in the firm’s catalog to Round Hill Music in 2014, but the two companies split future ­signings. Wiseman credits England with keeping his Big Loud publishing and artist management operations running at peak performance, saying, “He’s the Scooter Braun of Nashville.”
